In 2410, Starfleet initiated revision 120.2C to the Starfleet Uniform Code. The 2386-2409 style of uniform was retired and replaced in favor of a new uniform code. Starfleet commanding officers had the option to specify a uniform style of their own for their crews, but unless otherwise specified by said COs all Starfleet personnel were to change to a new style, dubbed "Odyssey". Fleet Admiral Jorel Quinn sent a memorandum to all starship and space station commanders containing detailed instructions on the new style on stardate 87003.8.
